Integer and Floating Point Throughput

SPEC* CPU2006 is a benchmark to measure system efficiency during integer and floating point operations. It consists of an integer test suite containing 12 applications and a floating point test suite containing 17 applications, which are extremely computing-intensive and concentrate on the CPU and memory. Other components, such as disk I/O and network, are not measured by this benchmark. SPEC CPU2006 contains two different methods of performance measurement: The first method "speed" determines the time required to complete a single task. The second method "rate" determines the throughput, i.e. how many tasks can be completed in parallel. Both methods are additionally subdivided into two measuring runs, "base" and "peak", which differ in the way the compiler optimization is used. The "base" values are always used when results are published; the "peak" values are optional. The chart below shows "Base" Integer Throughput performance as measured by SPECint*_rate_base2006.
